Very nice attempt Hood, but actually somewhat confusing, as it's actually not as much a "list of Polish project numbers" but rather "list of project numbers and design acronyms of ships built and used in Poland".
Indeed each country used it's own project number sequence , but they were to an extent interchangeable in the sense that ships built in one country for another had only one project number (rare exception being the missile boat designated by NATO as BAL-COM 10, which was Pr.151 in East German sequence and Pr.660 in Polish sequence).
The numbers on the list actually belong to three groups, only two of them (or one-and-a-half) is actually Polish.
1) ships built in Soviet Union (like Pr.205 or Pr.877 for example) or Hungary (Pr.101) and/or built in Poland under license which kept their original "foreign" project number (occassionaly with only an additional post-number letter for local design modification);
2) ships built in Poland for foreign - most often Soviet - order (either only for export - Pr.775 for example, or both for export and domestic use - Pr.770-family for example), having the same project number in both sequences (Polish and Soviet);
3) actual "Polish project numbers" (Pr.207, for example).
Next thing are the project numbers with B-letter (Pr.B410 or Pr.B-410 depending on source). Generally these refer to civilian vessels, but with a caveat: the military project numbers were confidential, but the construction of any vessel involves of numerous sub-contractors, often delivering relatively trivial elements, therefore the "military-ordered ships" had, besides their main (confidential) project number, the secondary ("public") project number with B letter, used as internal designation of the design bureau and for contacts with sub-contractors, which thereby didn't need to know the "actual" designation.
And finally, the last group on the list - besides containing the D-3 which is simply a non-Pr. Soviet designation, it contains some ships that generally belong to the "basic" lists as their extensions (like NS-717 or NS-723, whose numbers belong to original sequence but after the post-1989 political changes no longer use the Pr. but use the NS- - for Navy Shipyard - instead) and some separate non-sequential designations like ST which was essentialy a correspondence cryptonym rather than the "usual project number". There are also some fishing boats there, but the details of their designations are as yet unclear for me - I have relatively recently acquired a very interesting book about Polish fishing boats (with lots of drawings - hint, hint
), but I didn't had the opportunity to read it yet.I'll try to eventually compile the list of Polish project numbers, but that's unlikely to happen too soon, I'm afraid.
P.S. - Not Pr.194BMO but Pr.194 BMO - BMO is a separate designation (Bronirovanny Malyi Okhotnik - Armored Small Submarine Chaser), not an extension of project number (like Pr.667B/BD/BRD/BDRM), as that would imply existence of earlier Pr.194B/BM.
